概括

风味 (KFR) 可能会改善耐力运动员在运动后的胃肠道舒适度. 这项研究发现,与牛奶或安慰剂相比,KFR可以减少主观的胃肠道症状,而不会影响5公里时间试验的表现.

科学领域:

运动营养运动营养
运动生理学运动生理学
胃肠病学胃肠病学

背景情况:

恢复营养对耐力运动员至关重要.
,一种发酵乳制品,是一种潜在的恢复饮料.
有限的研究存在于对炼引起的胃肠道疾病的影响.

研究的目的:

为了比较调味 (KFR) 和调味牛奶 (MLK) 作为主耐力运动员的恢复饮料.
评估KFR和MLK对5公里计时赛表现的影响.
评估KFR和MLK对胃肠道症状和肠脂肪酸结合蛋白 (I-FABP) 水平的影响.

主要方法:

随机,安慰剂控制,非盲目的交叉研究,共11名参与者.
参与者完成了三次测试访问,在耗尽性运动 (EE) 后摄入KFR,MLK或安慰剂 (PLA).
胃肠道症状评分表 (GSRS) 和I-FABP水平在运动后进行测量.

主要成果:

在KFR,MLK和PLA条件之间没有观察到5公里计时试验性能的显著差异.
在EE后,KFR组报告的GSRS总得分明显低于PLA组 (p = 0.005).
在所有条件中,没有发现I-FABP水平的显著差异.

结论:

急性KFR补充剂没有提高计时试验的表现或改变I-FABP水平.
在强度炼后,KFR可能有助于减少主观胃肠道症状.
风味酒为经历胃肠道不适的耐力运动员提供了可行的恢复选择.

Exercise and Muscle Performance

Exercise and Muscle Performance

Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

Muscle Recovery and Fatigue

Muscle Recovery and Fatigue

Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...
